Recent research has elucidated its pivotal role in innate immunity of crustaceans, enhancing the immune response by promoting phagocytic activity, antimicrobial peptide production, and modulation of immune gene expression. Copper ions exhibit antimicrobial effects by disrupting cell membranes and inhibiting microbial proliferation. Furthermore, copper governs antioxidant defense mechanisms, protecting crustaceans against oxidative stress and infection. However, excessive copper can lead to toxicity, highlighting the need for strict maintenance of copper homeostasis. This review explores the complex processes of copper homeostasis in crustaceans, detailing transport mechanisms, storage proteins, and detoxification pathways. It emphasizes copper's critical physiological and immunological functions, contributing to a comprehensive understanding of its multifaceted roles in crustaceans and laying groundwork for further exploration of copper homeostasis as a strategy for boosting crustacean immunity.

Modes of cell death like apoptosis, necroptosis, and necrosis are well-documented in crustaceans, serving crucial roles in removing damaged or infected cells. Unlike in other organisms, crustaceans likely lack pyroptosis, a type of programmed cell death associated with innate immunity and inflammation, because they do not possess the gasdermin genes essential for this process. Recently, NETosis and ferroptosis have emerged as significant mechanisms in pathogen defense. NETosis, involving the release of DNA fibers and antimicrobial proteins, helps trap and neutralize pathogens, while ferroptosis, an iron-dependent form of cell death, contributes to lipid peroxidation and immune responses. Cuproptosis, although not yet studied in the context of crustacean immunity, shows potential crosstalk with ferroptosis, particularly in the regulation of metal ion homeostasis, oxidative stress, and cellular metabolism. Understanding these mechanisms offers promising applications in aquaculture, such as developing targeted immune modulators and enhancing disease resistance in economically important crustacean species.</p>\u0000 </div>","PeriodicalId":227,"journal":{"name":"Reviews in Aquaculture","volume":"17 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142171403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both distant hybridization and gynogenesis techniques can alter genotypes and phenotypes, thus establishing them as significant breeding methods. Additionally, the genetic principles and the basic biological characteristics of distant hybridization and gynogenesis in fish have been inferred. We propose the concepts of macro-hybrid and micro-hybrid based on extensive experimental findings from fish distant hybridizations and gynogenesis. The term “macro-hybrid” refers to offspring from distant hybridization that possess two distinct subgenomes, each inherited from one of the two parental species, such as allodiploid and allotetraploid lineages. The concept of “micro-hybrid” refers to offspring, including autodiploid and autotetraploid lineages, as well as those resulting from artificial gynogenesis, whose genome almost originates solely from the maternal parent but in which certain DNA fragments derived from the paternal parent insert.

Here, we present a review of the current progress in fish genomics and its application in disease-resistance breeding. First, assembly data for all publicly available fish genomes were curated and statistical analysis of these data were performed. Subsequently, genomics-assisted breeding approaches (including quantitative trait loci mapping, genome-wide association study, marker-assisted selection, genomic selection, gene transfer, and genome editing) that have been applied in practical disease–resistance breeding programs are outlined. In addition, candidate genetic markers that could possibly be utilized in breeding were summarized. Finally, remaining challenges and further directions were discussed.

It is not surprising therefore that nutrition-related disorders still remain the number one preventable health challenge facing all countries globally: over 735 million people suffering from hunger and under-nutrition in 2022, and over-nutrition and obesity, and resulting metabolic disorders such as coronary heart disease, diabetes and hypertension, resulting from the increased consumption of fast foods and processed meat products, affecting over 890 million adults in 2022 [<span>1</span>].</p><p>Notwithstanding the above global crisis, aquatic food products, whether derived from aquaculture or wild capture fisheries, offer a much healthier alternative to fast foods, highly processed foods and terrestrial meats [<span>2</span>]. Aquatic foods include freshwater and marine fish, crustaceans, molluscs, and several other invertebrate species, such as sea urchins, sea cucumbers, sea squirts, marine worms, as well as aquatic plants, seaweeds, and algae. According to the latest statistical information from the FAO, total global aquaculture production in 2022 reached a new high of 130.92 million tonnes (Mt, live weight) and was valued at $312.75 billion, with the total global production increasing at a compound annual growth rate of 5.19% per year since 2000.

The present review aims to summarize the existing findings regarding the effects of studied alternatives to fishmeal and fish oil on the most valuable and commercially produced marine (<i>Sparus aurata</i> and <i>Dicentrarchus labrax</i>) and freshwater (<i>Salmo salar</i> and <i>Oncorhynchus mykiss</i>) finfish species in European aquaculture.

Applicability of these ingredients is reviewed in terms of nutrient composition, dietary inclusion level, performance output, digestibility, and health benefits. In addition, a meta-analysis was conducted based on data from peer-reviewed scientific publications in order to assess whether novel ingredients meet the dietary protein (amino acid) and lipid requirements of finfishes. Aquafeed reformulation strategies should ensure the recommended daily nutritional requirements and additionally indicate the meta-analysis alternatives, such as microalgae, which are deficient in essential amino acids.
